Spokesmen for the police department and the Mayor’s office confirmed today that a special 24-hour police patrol has been in effect at Khal Adath Sochochow synagogue in Boro Park since an anti-Semitic attack there on congregants occurred Yom Kippur night. The police spokesman said the patrol would continue indefinitely. According to reports earlier this week from residents in the Boro Park area, the special patrol had been removed this past weekend. Although the Jewish Defense League was reported to have set up its own patrol, a source close to the synagogue said that its members were no longer visible. District Attorney Eugene Gold told the Jewish Telegraphic Agency today that he was giving the “tense” situation “special attention,” and that he had received “a commitment from the police” to keep special watch over the area. On Oct, 10, at Day of Atonement services at the Orthodox synagogue, young congregants were attacked by 50 Puerto Rican youths who insulted them and threatened “blood and revenge.” One of the two assailants subsequently arrested was scheduled to appear in court today.
